Extensions

Based on my analysis of U.S. Patent 12,231,703 as of May 1, 2026, here are the details regarding its term, related applications, and family members.

Patent Term Adjustment (PTA) and Patent Term Extension (PTE)

• Patent Term Adjustment (PTA): The provided documentation from Google Patents does not specify the exact number of days of Patent Term Adjustment granted by the USPTO for delays during prosecution. PTA is awarded on a day-for-day basis for certain administrative delays by the USPTO. While this information would be available in the USPTO's official file wrapper, it is not present in the provided source materials.
• Patent Term Extension (PTE): There is no indication that this patent has received or is eligible for a Patent Term Extension. PTE is typically granted to compensate for regulatory review delays (e.g., by the Food and Drug Administration) for products such as pharmaceuticals and medical devices, and is not applicable to the technology covered by this patent.

Continuation and Divisional Applications

The prosecution history of this patent involves a chain of continuation applications.

• Continuation Applications: U.S. Patent 12,231,703, which issued from application Ser. No. 18/480,918, is part of a series of continuing applications.
  • It is a continuation of U.S. application Ser. No. 17/454,169 (now U.S. Patent 11,825,139).
  • Application Ser. No. 17/454,169 is itself a continuation of U.S. application Ser. No. 16/645,598 (now U.S. Patent 11,184,652).

Related Patent Family

U.S. Patent 12,231,703 is part of a larger patent family (Family ID 65634196) with members in the United States and other countries. The U.S. patents in this family include:

• U.S. Patent 11,184,652: Issued from application Ser. No. 16/645,598.
• U.S. Patent 11,825,139: Issued from application Ser. No. 17/454,169.
• U.S. Patent 12,231,703: The patent in question, issued from application Ser. No. 18/480,918.

The family also includes patent applications and grants in other jurisdictions, including Europe (EP), China (CN), Brazil (BR), and Taiwan (TW), stemming from the international PCT application WO2019050660A1.

Projected Expiration Date

The term of a U.S. patent is typically 20 years from the filing date of the earliest U.S. or international (PCT) application in the priority chain.

• Earliest Effective Filing Date: The patent's priority chain traces back to PCT Application No. PCT/US2018/046723, which was filed on August 14, 2018.
• Calculated Expiration Date: The 20-year term, calculated from this effective filing date, ends on August 14, 2038.

This date aligns with the "Anticipated expiration" date provided in the patent's documentation. This suggests that there were zero days of Patent Term Adjustment (PTA) granted, as the expiration date is exactly 20 years from the earliest effective filing date.
